Subject: [PATCH net 0/2] inet: use siphash in exception handling
Date: Wed, 25 Aug 2021 16:17:27 -0700	[thread overview]
Message-ID: <20210825231729.401676-1-eric.dumazet@gmail.com> (raw)

From: Eric Dumazet <edumazet@google.com>

A group of security researchers brought to our attention
the weakness of hash functions used in rt6_exception_hash()
and fnhe_hashfun()

I made two distinct patches to help backports, since IPv6
part was added in 4.15

Eric Dumazet (2):
  ipv6: use siphash in rt6_exception_hash()
  ipv4: use siphash instead of Jenkins in fnhe_hashfun()
